@shim2dawg once my teacher taught me how to do those dotted lines.... i'm not sure if i can explain it properly in english... but i'll try. You just have to hold the chalk firmly at the tip, or at least near the tip (by tip i mean the extreme opposite to the point that is actually touching the blackboard), and then slide the chalk fast and hard in the direction you want to draw the dotted line. One thing that helps is that the tip that is touching the board should be as flat as possible...

Walter Lewen teaches you to always be aware of an infinite number of impossibilities as well as known possibilities and those which may not yet be known. This is not a robot factory. It's a probability factory.
